Abstract: A shift register includes a forward/backward scan-control module, configured to transmit a signal of a forward-scan-signal terminal or a signal of a backward-scan-signal terminal to a first node; an interlock module, configured to transmit a signal of a first voltage terminal to a second node, and transmit a signal of a second voltage terminal to the first node; a pull-down module, configured to transmit the signal of the first voltage terminal to a gate-signal output terminal; an output module, configured to transmit a signal of a second clock-signal terminal to the gate-signal output terminal; and a reset module, configured to transmit the signal of the second voltage terminal to the first node, and transmit the signal of the first voltage terminal to the gate-signal output terminal. The disclosed shift register can prevent leakage of the first node, and thus improve the quality and the performance of the shift register.
